Node Behavior Trust Evaluation Model Based on Sliding Window

In order to improve confidence of the node behavior the credibility assessing, this paper presents the nodes behavior of the trust evaluation mechanism based on sliding window, Through the sliding window Assessment strategies to ensure the trust assessment to meet the node behavior assessment principles, Assessment strategies is good combination of confidence assessment method of the subjective and assessment content of the objectivity to ensure contacts number ofa large number of nodes (Nmin) at the same time maintaining good scalability, trust assessment reflects the importance of the recent behavior and the attenuation of long-term behavior, with a "slow rise" and "fast drop" feature, the algorithm with good against fraud and punishment of malicious nodes .
